Objective　To analyze the surgical results of uveitis-complicated cataract.Methods　Cataract phacoemulsification surgery was performed on 31 eyes (29 patients) due to uveitis (iridocyclitis 14 eyes, Fuchs heterochromic cyclitis 7 eyes, intermediate uveitis 7 eyes, Vogt-koyanagi-harada syndrome 2 eyes, and sympathetic ophthalmia 1 eye). Follow-up period was 5～28 months, averaging 15 months. Retrospective analysis was made.Results　Postoperative visual acuity≥0.5 was 80%. One eye (Vogt-koyanagi-harada syndrome) showed severe anterior uveitic reaction; One eye (iridocyclitis) had fibrinous membranes on IOL, and white debris on IOL were found in 2 eyes (intermediate uveitis).Conclusion　By using less traumatic phacoemulsification technique to ocular tissue, taking meticulous care to avoid stimulating iris, cleaning up cortex thoroughly during surgery and implanting the IOL in the bag, less inflammatory reaction, less complication and better vision acuity postoperatively at relative quiescence period of uveitis can be achieved.

Objective:To investigate the contrast-enhanced ultrasound (CEUS) features of inflammatory hepatocellular adenoma (I-HCA).Methods:The contrast-enhanced ultrasound features I-HCA of 28 cases from April 2009 to November 2019 in Zhongshan Hospital, Fudan University were retrospectively analyzed, including arterial phase enhancement pattern, the homogeneity of enhancement, subcapsular enhancement, and the internal perfusion defect. All I-HCA lesions were divided into >5 cm group( n=9) and ≤5 cm group( n=19), the CEUS features between the two groups were compared. Results:All I-HCA lesions were hyper-enhanced in the arterial phase, among which 39.3% (11/28) showed diffuse filling, 39.3%(11/28) showed centripetal filling, and 21.4%(6/28) showed centrifugal filling pattern. Twenty-five percent (7/28) of I-HCAs showed heterogeneous enhancement, 10.7% (3/28) revealed unenhanced areas within the lesions. Subcapsular vessels were observed in 67.7 (21/31) of I-HCA lesions. Heterogeneous enhancement and unenhanced areas were more frequently detected in lesions >5 cm ( P=0.020, 0.026, respectively), while there was no difference in the enhancement pattern and subcapsular vessels between the two groups ( P>0.05). Inportal venous phase, 42.9%(12/28) of I-HCAs showed hypo-enhancement, and 57.1%(16/28) of lesions showed washout in late phase. According to "hyper-enhancement in arterial phase, sustained hyper- or iso-enhancement in portal venous and late phase" by CEUS, the diagnostic accuracy of benign lesion was 42.9%(12/28). According to any of hyper-enhancement pattern in arterial phase, subcapsular vascular enhancement, and sustained hyper- or iso-enhancement in portal venous and late phase, the diagnostic accuracy of I-HCA was 71.4% (20/28). Conclusions:CEUS is valuable in the diagnosis of inflammatory hepatocellular adenoma.

Objective: To investigate the clinical and prognosis value of left ventricular diastolic function(LVDF)in predicting the short-term prognosis of sepsis-associated acute lung injury/acute respiratory distress syndrome(ALI/ARDS)in the elderly. Methods: This was a prospective case-control study.A total of 93 elderly patients with sepsis-associated ALI/ARDS, who admitted to our hospital between February 2015 and February 2018, were selected as the study subjects.And they were divided into ALI group(n=52)and ARDS group(n=41). Meanwhile 50 elderly sepsis patients without ALI/ARDS were selected as the control group.Based on the prognosis at the 28th days of admission, patients with ALI/ARDS were divided into a death group and a survival group.General clinical data and left ventricular diastolic function index at different time points after admission were compared between groups. Results: There were statistically significant differences among the ALI group, ARDS group and control group(P<0.05)on admission and at 3 and 7 days after admission in the parameters as the following: heart rate, mean arterial pressure(MAP), acute physiology and chronic health evaluation system Ⅱ(APACHEⅡ)score, acute lung injury score(LIS), oxygenation index(PaO₂/FiO₂), arterial blood lactic acid, blood glucose, serum creatinine, troponin I, B-type brain natriuretic peptide(BNP), procalcitonin(PCT), C-reactive protein(CRP)and early diastolic transmitral velocity to early mitral anulus diastolic velocity ratio(E/Em). APACHEⅡscore, LIS score, blood glucose, troponin I, BNP, PCT, CRP and E/Em were higher in the death group than in the survival group on admission and at 3 and 7 days after admission(all P<0.05). Multivariate logistic regression analysis showed that E/Em on admission and at 3 and 7 days after admission were the independent predictors for mortality in patients with sepsis-associated ALI/ARDS(OR=1.346, 2.150 and 1.954, respectively, P<0.05). ROC curve analysis showed that the area under curve(AUC)of E/Em for predicting death on admission and at 3 and 7 days after admission were 0.687, 0.840 and 0.771, respectively, with the optimal threshold value of 13.26, 14.90 and 14.62, respectively, and the sensitivity and specificity were 74.2% and 67.1%, 81.5% and 84.2%, 79.1% and 87.8%, respectively, .The mortality rate was higher in patients with E/Em above the optimal threshold value than below the optimal threshold value at each time point(all P<0.05). Conclusions The impairment of LVDF is serious in elderly patients with sepsis-associated ALI/ARDS, may be an independent predictor for recent death in such patients, and has a good predictive value for the prognosis of elderly patients with sepsis-associated ALI/ARDS.

Objective: To evaluate the feasibility of quantitative analysis of dynamic 3-dimensional contrast-enhanced ultrasound (3D-CEUS) for treatment effects of microwave coagulation on xenograft tumors in nude mice. Methods: BALB/c nude mice transplanted of HepG2 cells were divided into treatment group(n=16) and control group(n=16). The tumors were treated by incomplete microwave coagulation in the treatment group when their maximum diameters were about 0.8~1.0 cm. The baseline ultrasound and dynamic 3D-CEUS were performed on 1 d before treatment, 3 d after treatment, 7 d after treatment and 14 d after treatment. Time-intensity curves of the tumors were obtained by fitting. The quantitative parameters were also obtained, including peak intensity (PI), time to peak (TTP), mean transit time (MTT), slope (S), area under the curve (AUC), area under the curve of wash-in (AWI), and area under the curve of wash-out (AWO). Results: There were significant differences(P=0.029) between the two groups in PI, S, AUC, AWO on 3 d and 14 d. The differences in other parameters were not statistically significant (P>0.05). On 1 d before treatment and 7 d after treatment, none of the parameters had statistically significant difference (P>0.05). Conclusions The quantitative analysis of dynamic 3D-CEUS is feasible to assess the treatment response on xenograft tumors in nude mice.

OBJECTIVETo perform a prospective,multicenter,open,randomized study to determine a treatment regimen for treatment-naive patients with refractory chronic hepatitis C (RHC) using the predictive value (PV) of early virological response (EVR).

METHODSA total of 438 patients from 18 hospitals were recruited between December 2008 and December 2010 and administered peg-interferon/ribavirin treatment for 12 weeks. Patients who achieved complete EVR (cEVR) were assigned to group A for a 48-week course of treatment, while patients without cEVR were randomly allocated to either group B 1 for a 72-week course of treatment or to group B2 for a 96-week course of treatment. Serum hepatitis C virus RNA levels at baseline,treatment weeks 4, 12 and 24, end of treatment, and post-treatment week 24 were measured and used to evaluate the efficiency of therapy.

RESULTSThe overall sustained virological response (SVR) rate was 85.1%. In all, 91.0% of patients achieved cEVR and were assigned to group A, which had an SVR rate of 90.8%. There was no statistically significant difference in the SVR rates of groups B1 and B2 (29.4% vs. 25.0%, P more than 0.05). The positive PV of rapid virological response (RVR), cEVR and delayed virological response (DVR) for SVR was 93.4%, 90.8% and 77.8% respectively, and the negative PV of RVR, EVR and DVR for SVR was 28.0%, 93.3% and 100% respectively. Overall, 66.9% of the patients experienced adverse events (AEs), but only 1.9% of patients experienced sevcre AEs.

CONCLUSIONThe majority of Chinese RHC treatmentna(i)ve patients (91.0%) can achieve cEVR and a high SVR rate with a low rate of severe AEs using the cEVR guided personal treatment regimen.

Objective To evaluate the imaging features of hepatic epithelioid angiomyolipoma (EAML) on contrast-enhanced ultrasound (CEUS). Methods The imaging features of pathologically proved hepatic EAML lesions in 17 patients who had undergone baseline ultrasound and CEUS examinations were evaluated retrospectively. Results All of the cases were single lesion.70.6% (12/17) of the lesions were hypoechoic on ultrasound and 82.4% (14/17) of the lesions were heterogeneous.Flow signals were detected in 88.2% (15/17) of the lesions and 82.4% (14/17) of the lesions showed ringlike or arc arterials peripherally on color Doppler flow imaging (CDFI).The value of RI was 0.38-0.56.On CEUS,all lesions exhibited remarkable hyperenhancement in the arterial phase. 29.4% (5/17) of the lesions showed branched enhancement,70.6% (12/17) of the lesions showed diffusely entire enhancement.Strong ring-like enhancement peripherally was detected in 29.4% (5/17) of the lesions.88.2% (15/17) of the lesions were detected homogeneously enhancement during the peak period on CEUS. Washout of contrast agent and hypoechogenicity to surrounding liver tissue during portal or late phase were observed in 41.2% (7/17) and 64.7% (11/17) of the cases retrospectively.Conclusions The combination of real-time CEUS and baseline US can improve the correct diagnosis of hepatic EAML.

Background: Matrix metalloproteinase-7 (MMP-7) is a proteolytic enzyme involved in wound healing, tissue remodeling by regulating a variety of extracellular matrix and non-matrix substrates, and is an important mediator of tissue damage during inflammation in inflammatory bowel disease (IBD). Aims: To investigate the clinical significance of MMP-7 in IBD. Methods: A total of 38 cases of colon biopsy samples from patients with IBD from January 2019 to January 2021 at the Second Affiliated Hospital of Zhengzhou University were collected, including 20 ulcerative colitis (UC) and 18 Crohn's disease (CD). The paracancerous tissues of 5 patients with colon cancer were served as the control group. The expression of MMP-7 in colon tissue was detected by immunohistochemical staining, and its correlation with C-reactive protein (CRP) and white blood cell (WBC) was analyzed. Results: Compared with the control group, the expression of MMP-7 was significantly up-regulated in both active UC group and severe CD group (P<0.05). The expression of MMP-7 was gradually up-regulated with the increase of severity. The expression of MMP-7 in severe UC and CD group was significantly increased than that in remission UC and CD group (P<0.05). No significant difference in the expression of MMP-7 was found between patients with different gender, age, and whether treated with anti-TNF-α agents (P>0.05). The expression of MMP-7 in colon tissue of patients with active IBD was positively correlated with CRP and WBC (P<0.001). Conclusions: The expression of MMP-7 is correlated with the activity and severity of IBD, but not correlated with gender, age, and whether treated with anti-TNF-α agents. To some extent, MMP-7 can indicate the severity of intestinal inflammation, and may be an important indicator of inflammatory activity in IBD.
